Solving Equations and Functions

Given: y is three times as big as x.

If x = 8 the y = ?

(a)  

How would you write y = 2x - 3 in function notation?

Let

$$h\left(x\right)=13-5x$$   What is $$h\left(5\right)=$$  ?

Given f(x) = x² - 1, what is the value of f(10)?

Using f(x) , g(x) , or h(x) instead of y is called using ......

$$7x+8=29$$

The first step to solve this equation is to ​ (a)   . The next step is to ​ (b)   . The answer is ​ (c)   .

$$f\left(x\right)\ =\ 3\left(3x\ -7\right)$$

If f(x) = 24, what is the value of x?

A-B = C

(solve for A)

$$g\ =\ 6x\ \ \ solve\ for\ x$$
